The mechanism is shown and described inv our application, Serial No. 724,680, filed October 8, 1912, to which application ref-- crence is had for the details of construction.

ln thev operation of the mechanisml the throat is moved from the position shown in Fig. '7 to the position shown in Fig. 8, and the feeding 'and cutting member is then moved from the position shown in Fig. 7 to the position shown vin Fig. 8 so as to feed. the string T into the driver passage. Thera after the feeding and cutting member is movedl to the right Fig. 8, the guide being supported against the action of the feeding and cutting member by the spring 71, and the three members 65, 78 and 95 cooperating rThe angular relation of the guide 65 and the throat 52 will cause a bend to be formed in the string T at a point where the lowest fastener joins the one above it. The feeding and cutting member 78 and the die 95 operate to out the string' above the head of the lowest fastener and just below the bend formed in the string. The parts are so constructed and arranged that the oint of the fastener will be slightly turned or deflected laterally as fully described in our applicationreferred to above. While the throat has been moved to the left, the awl has formed a hole and placed this hole in the line of drive as shown in FigQS. Thereafter the awl is retracted and the throat with its fastener is moved to the left to place the driver passage in the line of drive and in alinement with the puncture, and the driver thereafter'descends to drive the fastener into the' stock as shown in Fig.

' 7, the fastener being clenched on the anvil 125. It will be understood that. the speciic mechanism is not absolutely essential for performing these operations, but other mechanism whether automatic or manually operated may be used for this purpose, and the operations may even be performed by simple tools.

The point 17 is slightly turned or deflected in the direction of the head 15 before it is driven to form an abrupt bend, therefore when this point strikes the anvil. it will be .turned or clenched in a predetermined direction of the deflected-point and, namely in the direction of thelaterally extending head 15. This preliminary preparation of the point will therefore insure that the fastener will be clenched in apredetermined direction. Anotherl factor which will insure such predeterminedrclench is due to the fact that the. Vcut edge c, is weaker than the uncut or invasie mechanically treated edge b. This will insure the clenching of the point in the direction of its weakest edge c, making the uncut edge Zi ,the outer orconvex edge of the then covered by turning down the channel fiap. The points 17 are clenched and turned back into the insole, and the point and the fastener itself are so formed, as described above, that the points as clenched and turned back by the clenching anvil will extend in the same direction and in a direction along the seam.' In the completed seam therefore the heads as well as the points will extend in the same direction and in a direction along the seam. At the shank of the shoe where the sole is thinner' than at the fore part, theof fish hook anchorage, the laterally de- -l flected point acting as a'barb to prevent the clenched point from working upwardly above the upper face pf the insole. The nail. is thus supported in the sole against movement either upwardly or downwardly. The nail will therefore wear uniformly with the sole and will not project beyond the face of the outsole even if the nail head is worn off. The beveled nail head does however assist materially to maintain the iirm grip of the seam. l

rlhe turning or delecting of the point is sufcientto predetermine the direction of clench, but is not sufcient lto cause the fase tener to curl or bend in the leather before it is driven and, before it strikes the clenching anvil This curling in hard stock is avoided by forming an awl hole or puncture which will guide and support the fastener while it is being driven. Care Inusthowever be taken to properly locate the awl hole "with respect to the fastener in the throat.

lf the lfastener has a tendency-to curl, then the awl hole should be placed sligh" the right Fig. .8;witl1' respect to the Ei' drive so as to overcome this tendency. The seam produced by this method will be exceedingly flexible as fully setforth in the application for the seam, Serial No. 647,263.

It Will thus be seen that the invention accomplishes its objects. A seam is produced which Will be practically as flexible as a sewed seam, but will possess better wearing qualities, and this seam can be .made in simple machines compared 'with the McKay seWin machine, and can be madeby nnskillecgl operators. The clenched points are turned back into the insole so that the inside face ot' the insole will be lett perfectly smooth since the projectingr point itself is buried 1n the leather, leaving only' a rounded part exposed on the 'face of the insole. The fish hook anchorage will moreover prevent the clenched points from Workii'ig up above the face of the insole. The sock sole usually required in McKay shoes may therefore be dispensed with. rilhe fasteners may be countersunk in the outsole,v and the holes can be closed in the leveling and scouring operationsJ so that the outsole will be lett smooth. The channel. and its accompanying' channeling operation can therefore be omitted,

thus resulting in a saving of cost oil manufact-ure.

Having thus described the invention what is claimed is:

l. The lnethod of attaching soles to shoes yby a metallic fastener seam which comprises presenting a plurality of fasteners having abruptly deflected points to the outsole with the deliected points extending in the same direction and in the direction ot the seam, inserting the' fasteners so presented through the outsole and insole, and clenchinthe points of said fasteners back into the insole in the direction of the deflected points,

'whereby said outsole and insole are secured by a row of fasteners having their points clenched and extending in the same direction and in the direction of the seam.V

2. The method oi attaching soles to shoes by a seam consisting of metallic fasteners which comprises abruptly dellecting the points of the fasteners an amount suflicient to predetermine the direction ofthe cleneh by a clcnching anvil but not sulicient to -cause the nail to curl while passing through the material, insertingIl the fasteners through the outsole and insole,- and clenehing the de ilected points by engagement with a clencl1- ing anvil back into the insole and in the direction ol their abrupt deflection, for the purpose set 'fort/h.

. The method ot' attaching soles io slices by a metallic fastener seam which comprises cutting a fastener from a string and simultaneously dellecting the point of the suc'- ceeding :lastener, severing said succeeding fastener from its successor and simultaneously dellecting the point ot said successor, presenting said severed fastener tothe outsole with its deflected point extending in the direction of the seam, inserting the tastener so presented through the outsole and insole, and elenching and turning the point back into the insole in the direction of its deflection, whereby said clenched point extends, in the direction ot the seam.

ln testimony whereof we allix our signatures in presence olA two witnesses.
